复合植物精油对蛋鸡生产性能及蛋品质的影响

Effect of compound plant essential oils on production performance and egg quality of laying hens

试验旨在研究饲粮中添加复合植物精油对蛋鸡生产性能及蛋品质的影响。选用体重相近、产蛋后期(362~368日龄)的大午金凤蛋鸡13664只,随机分为2组,对照组和复合植物精油组,每组4个重复,每个重复1708只。对照组蛋鸡饲喂基础饲粮,复合植物精油组在基础饲粮中添加复合植物精油。正式试验期14 d。结果表明,与对照组相比,复合植物精油组蛋鸡的产蛋率显著提高(P<0.05),平均蛋重有增加的趋势(P>0.05),沙壳蛋率显著降低(P<0.05),料蛋比降低(P>0.05)。与对照组相比,复合植物精油组鸡蛋的蛋黄比例显著降低(P<0.05),蛋壳强度有升高趋势;复合植物精油组鸡蛋的蛋黄颜色、硬度、湿润感显著提高(P<0.05)。研究表明,饲粮中添加复合植物精油可以提高蛋鸡的生产性能及蛋品质。

The experiment was conducted to study the effect of compound plant essential oils on the production performance and egg quality of laying hens.A total of 13664 Dawu Jinfeng laying hens with similar body weight and late laying period(362~368 days of age)were randomly divided into two groups,a control group and a compound plant essential oil group,with four replicates in each group and 1708 laying hens in each replicate.The laying hens in the control group were fed a basal diet,and the laying hens in the compound plant essential oils group were fed a basal diet supplemented with compound plant essential oils.The trial period was 14 days.The results showed that compared with the control group,the laying rate of laying hens in the compound plant essential oils group was significantly increased(P<0.05),the average egg weight showed an increasing trend(P>0.05),the sand shell egg rate was significantly decreased(P<0.05),and the feed to egg ratio was decreased(P>0.05).Compared with the control group,the egg yolk ratio of the compound plant essential oils group was significantly decreased(P<0.05),and the eggshell intensity had a rising trend.The egg yolk color,hardness,and wetness in the compound plant essential oils group were significantly increased(P<0.05).The study indicates that adding compound plant essential oils to the diet can increase the production performance and egg quality of laying hens.
